Isaac was the first person to give a lecture? Professor barrow. Barrow is an outstanding mathematician and a pioneer of calculus. He also has high attainments in physics, astronomy and optics. It can be said that Barrow was a mentor and friend who changed Newton's scientific path.

After Barrow gave a lecture about Lucas, Newton admired his talent even more and listened to every lecture. Barrow's lecture style is free, active and inspiring, which aroused Newton's great interest. He never found science so interesting and there were so many infinite mysteries that Newton was deeply attracted. At the same time, Newton's extraordinary understanding of mathematics also left a deep impression on Barrow.

Inspired by Professor Barrow, Newton began to read a lot of natural science and philosophy works widely. From Galileo's interstellar messenger to Kepler's optics to Descartes' geometry, Newton wandered freely in the ocean of knowledge, eagerly studying and learning all scientific inventions and achievements since the modern scientific revolution.

Lucas' lecture, Descartes' geometry and Wallis' arithmetica infinitorum led Newton to stride forward to the door of natural science. From then on, Newton really began his scientific career.

Professor Barrow is a genius. However, as far as human history and scientific history are concerned, his real greatness lies in discovering the great genius-Newton, and giving this genius a chance to play. Gradually, Newton established a close relationship with Professor Barrow, who was 12 years older than him. They are teachers, students and good friends. Professor Barrow admired Newton's cutting-edge achievements and extraordinary understanding of natural science and mathematics. In order to make Newton achieve greater achievements, Barrow selflessly passed on all his experience and knowledge to Newton.
